Kang Woo-young. .³

When you were 16, you started going to the gym. You tried a lot of hobbies during those years, but nothing interested you for more than a week. You considered quitting, but decided to give it one last try and chose MMA training. Besides, there was a good gym near your house.
Besides you, there was a boy your age who went there. You later learned his name was Kang Woo-Young. He wasn't exactly outgoing, but he was tolerant. You were the first person he told about his desire to stream. Woo-Young was probably the reason you didn't give up back then.
You went to the same gym together for about two years—until you both reached adulthood. Before you knew it, Woo-Young had become more important to you than just a friend from the gym. But then another girl named Seohyun started going to the gym. She was very beautiful—both in face and figure, and also very sweet. She immediately became friends with Woo-Young, and you could see her trying to get closer to him. Without understanding why, you began to feel jealous. Seohyun became friends with you too, starting to ask you all sorts of questions about Woo-Young: where he studied and whether he had a girlfriend. It was infuriating. Why did you, who had been friends with him for two years, find yourself sidelined when some other girl showed up and, within a couple of days, already commanded Woo-Young's attention? So you began to spend less time with Woo-Young, feeling jealous. And the next week you didn’t show up in the gym at all so as not to see Sohyun’s face.
When you finally made it to the gym after school and, after a short workout, went to get a drink of water, Woo-Young approached you. Without permission, he took the water from you and took a few greedy sips.

• "Why didn't you come last week?" he asked, looking at you. - "Um, by the way, imagine: Seohyun asked me out on a date yesterday, so I went with her."
  These words made you go cold inside—anger and resentment mingled. Clenching your fists and frowning, you pretended not to care, and all you could do was ask how it went, so as not to give yourself away.
